Description

"Clip for attaching an element to another element and use of such a two-part clip"

The invention relates to a clip for fixing an element to another element, in particular a two-part clip, and a device having a first element and a second, attached to the first element by means of a clip element and the use of a clip.

One-piece clips for attaching a first element to another element are known in the art. WO 2012/104250 A1 describes, for example, a one-piece clip with a head and a shaft extending from the head along a shaft axis and having a point. On the shaft of the known from WO 2012/104250 A1 clip a total of four projections are provided, each having a head facing contact surface (clip surface). The projections are resiliently biased in a direction perpendicular to the shaft axis and pass through recesses provided on sides of the shaft. The clip known from WO 20/104250 A1 has arms provided as part of the head and protruding from a main body of the head. In the end region of the respective arm, in each case a contact surface of the head is provided, which faces the projections. As can be seen from FIG. 5 of WO 2012/104250 A1, the one-piece clip described there attaches an attachment 30 in the form of an airbag arrangement as a second element attached to a mechanically highly resilient support member 29 as a first element. The clip known from WO 2012/104250 A1 is a one-piece component which is produced by bending over sections of a metal section. A disadvantage of the clip known from WO 2012/104250 A1 is that the metal element damages one of the elements to be fastened together. Furthermore, the clip known from WO 2012/104250 A1 is not suitable for applications in which one or both of the elements to be fastened together has a hole which is penetrated by the clip but which is to be sealed against ingress of liquid, for example when the clip is attached thereto is used to attach a panel to a vehicle frame.

Against this background, the object of the invention was to propose a clip for fastening a first element to a second element, in which the risk of damaging one of the two elements to be connected to one another is reduced and / or which enables a seal to be sealed in a element he goes through.

This object is solved by the subject matter of claims 1 and 11 and the device according to claim 15 and the use of such an object according to claim 10. Advantageous embodiments are given in the subclaims and the following description.

According to a first aspect, the invention is based on the basic idea of providing, in addition to a known one-piece clip, another component in the region of the head of such a clip, which can prevent damage to the elements to be connected and / or bring about a sealing effect and / or or other positive effects, such as the generation of a biasing force can cause.

To this end, the invention provides a two-part clip having a first component having a head and a shaft extending from the head along a shaft axis and having a tip, at least one projection being provided on the shaft facing the head Contact surface, and the head has a projection facing the contact surface. The projection may be resiliently biased in the direction perpendicular to the shaft axis. The projection may be designed to be movable in the direction perpendicular to the shaft axis. Furthermore, the invention provides for the two-part clip a second component with a contact surface of the head facing support surface, on which the contact surface of the head is supported, and a projection facing the contact surface. The second component may be designed in the simplest embodiment as a kind of washer, it not being necessary that the second component has an opening through which the shaft extends, although this is proposed in a particularly preferred embodiment. It is also conceivable that the second component is provided in the form of a pad, which is assigned to a specific contact surface of the head. For example, it is conceivable for the head to have a plurality of contact surfaces and for each contact surface to provide a component with a support surface facing the respective contact surface of the head, on which the respective contact surface of the head is supported, wherein the respective component has a contact surface facing the projection having.

A "clip" for attaching a first element to a second element is understood to mean a fastening device which has at least one first contact surface and at least one second contact surface facing the first contact surface The first contact surface is generally provided on a stationary element of the fastening device While the second contact surface is provided on a resilient element of the fastening device, such fastening devices are intended to be inserted with a point into a recess, usually a hole, in the first element, during which the resilient element carrying the second contact surface is inserted The first element is usually formed as a flat element, for example as a plate or as a sheet metal of a part of a frame of a vehicle However, also have a blind hole with a correspondingly selected undercut, which allows the resilient element rebound after it has passed a narrower part of the hole above the undercut. The second member may be clamped to the first member, such as when it is slid between a head of the clip and a surface of the first member, and the distance of the first contact surface then provided on the head of the clip and the second contact surface of the clip Clips is selected so that they can produce such a clamping at a certain material thickness of the first element and a certain thickness of the second element. It is also conceivable that the second element also has a hole and the clip is guided with its tip through both holes. It is also conceivable that the second element is attached to a head of the clip, for example, if this has a hook or a mounting mushroom or if the second element simply glued to the head of the clip, welded or otherwise mating connected. This general understanding "clip" is further concretized for the first aspect of the present invention in that the above-mentioned second contact surface here is the head-facing contact surface of the projection on the shaft and the contact surface referred to above as the first contact surface on the second component provided, the projection facing contact surface. A head of such a clip is understood to mean a widening provided at one end of the clip. The head is usually designed to prevent the clip from being pushed all the way through a hole in the first element. Often, the head is also designed to apply the applied for the insertion of the clip in a hole of the first element force on the clip can. For this purpose, the clip often has a flat surface facing away from the tip. In a preferred embodiment, the head is rigid, "rigid" meaning that no portion of the head is movable relative to another head, for example resiliently formed.In an alternative embodiment, the head has a rigid base on which to In a preferred embodiment, the largest cross-sectional area of all cross-sectional areas of the head in planes perpendicular to the longitudinal axis of the clip is greater than the largest cross-sectional area of all cross-sectional areas of the shaft in planes perpendicular to the longitudinal axis of the clip.

The clip also has a tip. In the context of this description, "tip" refers to only the end of the clip opposite the head, although in a preferred embodiment it is provided that a shank of the clip extending from the head towards the tip tapers towards the tip but not necessarily a tip in the context of this description is also understood to mean a blunt end in a conceivable embodiment at the end of a shaft opposite the head .. In a preferred embodiment the tip may be pyramidal or conical or truncated pyramidal or frustoconical However, this is not essential, the tip may be formed by a single portion of the clip, but in a preferred embodiment, the tip will be a a plurality of sections of the clip formed, for example, by the four vertices of the arcuate Umbiegeabschnitte 15, as shown in WO 2012/104250 A2 or the two vertices of the arc sections of in Fig. 1, 2, 7, 8, 9, 10 of Embodiments shown EP 2 404 067 B1.

Between the head and the tip of the clip has a, possibly composed of several parts shaft. The clip has a longitudinal axis extending from head to tip. Particularly preferably, the shaft is longer in its longitudinal extent pointing from head to tip than in a width direction pointing perpendicular to the longitudinal extent. Particularly preferably, the longitudinal axis (the shaft axis) of the clip in the direction of the longitudinal extent of the Shaft. In a preferred embodiment, the clip is mirror-symmetrical with respect to a plane containing the longitudinal axis of the clip. In an alternative embodiment, the clip is rotationally symmetrical in that there is at least one plane, - which contains the longitudinal axis of the clip, in which each section of the clip, which is on one side of this plane, by a rotation of 180 ° can be brought into coincidence with an identically shaped portion of the clip on the other side of this plane about the longitudinal axis.

The clip according to the invention has a projection on the shaft. In particular, the projection preferably has a rest position in which it protrudes from a partial region of the shaft, for example one side of the shaft, and out of which the projection can be moved under force, in particular preferably in a direction perpendicular to the shaft axis (longitudinal axis) a direction parallel to a perpendicular to the shaft axis (longitudinal axis). Particularly preferably, the projection is connected to a resilient element or part of a resilient element, so that the projection must be moved under the action of force against an increasing spring force from the rest position and the spring force causes the projection returns to its rest position after elimination of the force. In a preferred embodiment, the rest position is the position in which the resilient element exerts no force. The rest position may, but need not be, defined by a stop against which the resilient element presses or pulls the projection. Particularly preferably, the projection in the direction perpendicular to the shaft axis (longitudinal axis) is resiliently biased. In a preferred embodiment, the resilient element engages a recess which is provided on one side and / or in the transition from one side to a side wall extending from the side towards an opposite side. In a preferred embodiment, the shaft has a second projection, which likewise has a contact surface (clip surface) facing the head. Particularly preferably, this second projection has a rest position in which it protrudes from a portion of the shaft, for example, a side of the shaft, and from which it can be moved under force, in particular preferably in a direction perpendicular to the shaft axis (longitudinal axis), or a direction parallel to a perpendicular to the shaft axis (longitudinal axis). Particularly preferably, the second projection is connected to a resilient element or part of a resilient element, so that the projection must be moved under the action of force against an increasing spring force from the rest position and the spring force causes the projection returns to its rest position after elimination of the force. In a preferred embodiment, the rest position is the position in which the resilient element exerts no force. The rest position may, but need not be, defined by a stop against which the resilient element presses or pulls the projection. This second one Projection is provided in a particularly preferred embodiment on one side of the shaft, which is opposite to a side on which the first projection is provided. In a particularly preferred embodiment, a total of four projections are provided, two on a first side of the shaft and two on an opposite side of the shaft, all four projections in the direction perpendicular to the shaft axis are resiliently, preferably preferably resiliently biased outwardly, or in each case with connected resilient elements or part of resilient elements, so that the respective projection must be moved under the action of force against an increasing spring force from the rest position and the spring force causes the projection returns to its rest position after elimination of the force. In a preferred embodiment, the rest position is the position in which the respective resilient element exerts no force. The rest position may, but need not be defined by a stop against which the respective resilient element pushes or pulls the respective projection.

In a preferred embodiment, the resilient element having the projection has a chamfer. The chamfer may be oriented so that the chamfer tapers in the direction of the spine. This allows the resilient member to come into contact with the tip in a hole of an element with the hole bordering the hole when the clip is inserted and pushed inward against the spring bias by this edge.

In a preferred embodiment, the second component has an opening through which the shaft is inserted. It is thereby achieved that the second component receives a certain definition with regard to its relative position to the first component. This leads in particular to a facilitation of the alignment of the second component relative to the first component, when the attachment of the one element to the other element is produced by means of the clip.

In a preferred embodiment, the second component is movable on the shaft loosely between a first position where the support surface abuts the contact surface of the head and a second position. In the second position, in a first embodiment, a protrusion or a protrusion on the second component can abut the edge of a recess of the first component, in particular in the shank of the first component. In a second, alternative or supplementary embodiment, the second component in the second position abuts against a protrusion of the shaft. In this way, a captive securing for the second component can be effected. In one direction, the second component is limited in its movement in that it rests with its support surface against the contact surface of the head. In the other direction, it is limited in its movement in that its elevation, or its projection against the edge of a recess in the first Component abuts and / or it abuts against a survey of the shaft. This elevation of the shaft may be a survey, for example a knob or a rib, specially introduced for the purpose of securing the second component. Likewise, the projection provided on the shaft anyway can form the elevation and limit the elevation of the second component in the direction away from the head. A captive securing of the second component offers the possibility of delivering the two-part clip already assembled to end customers. These can use the clip immediately and does not have to push the second component on the shaft of the first component in a first step, if a second component is provided with an opening through which the shaft is inserted.

In a preferred, alternative embodiment, the size of the opening in the second component and the cross-section of the shaft in the region in which it is inserted through the opening are chosen such that an interference fit between the second component and the shaft in the region of the opening of the second component arises. Such a press fit can help to create a sealing effect. A press fit in this area can also be produced by virtue of the fact that the second component has a sealing ring, or a resilient material producing a sealing effect, as the limiting border of its opening.

In a preferred embodiment, the second component has a recess which receives the head. As mentioned above, it is conceivable in a very simple embodiment that the second component is designed as a simple washer. Particular advantages are achieved, however, if the second component has a recess which receives the head. On the one hand, an even better positioning of the second component relative to the first component can thereby be effected. Furthermore, the inclusion of at least parts of the head in a recess of the second component may result in edges or sharp protrusions being covered on the head and thus no longer leading to damage to the elements to be connected to the clip. The recess can be chosen significantly larger in its three-dimensional shape, as the three-dimensional shape of the part of the head, which is to receive the recess. Already hereby, a protective effect against damage of the elements to be joined together can be achieved. In a preferred embodiment, the three-dimensional shape of the recess corresponds to the three-dimensional shape of the part of the head which it is intended to receive; The recess is preferably at least in terms of its outer contour, the negative of the part of the head, which it is to receive. As a result, the position of the head relative to the second component is clearly defined. Furthermore, such an embodiment may contribute to the sealing. For fixing the head, it may be sufficient if the recess with respect to its outer contours is the negative of the recorded by her head. The head can Undercuts or recesses have. Although they can be taken up in a preferred embodiment in the shaping of the recess and simulated as a negative. However, it is sufficient to achieve a positive, the head-locking effect, if only the outer contour of the recess of the outer contour (the envelope / Envelope) of the head is modeled.

In a preferred embodiment, the recess is formed so deep that when the contact surface of the head is supported on the support surface of the second component, the head does not protrude from the recess. In a preferred embodiment, the support surface of the second component is the bottom of the recess. This embodiment causes the head disappears entirely in the second component and is accessible only from above. As a result, a particularly good protection of the components to be connected with the clip is achieved.

In a preferred embodiment, in which the second component has a recess which receives the head and in which the second component has an opening through which the shaft is inserted, the opening of the second component extends from the bottom of the recess.

In a preferred embodiment, the recesses and the head have a rectangular cross-section. In this way, a rotation of the head relative to the second component can be prevented. In an alternative embodiment, the recesses and the head may have a circular, an elliptical, a triangular or polygonal cross-section, wherein the cross-section of the recess in a preferred embodiment corresponds to the cross-section of the head, so that the recess receive the head in a preferred embodiment without play can.

In a preferred embodiment, the first component and the second component are made of different materials. In a particularly preferred embodiment, the first component is made of metal, while the second component is not made of metal, wherein the second component is particularly preferably made of plastic. By means of this embodiment, the first component and the second component can assume different functions. The first component made of metal leads to a particularly high rigidity of the two-part clip. The execution of the second component not made of metal can be used to take with the second component damping, sealing or the elements to be connected protective functions. In an alternative embodiment, the first component and the second component made of the same material, particularly preferably made of metal or more preferably made of plastic. If the second component is made of a more elastic material than the first component, and more preferably also of a more elastic material than the material used for the two elements to be connected, the provision of the second component can also be used as tolerance compensation for manufacturing tolerances , If the distance between the contact surface facing the head of the projection and the contact surface of the second component facing the projection is selected to be smaller than the total thickness of the first element and the second element, if they are to be fastened together by the clip according to the invention, that between These two contact surfaces are arranged so the second component is compressed when generating the attachment and can thus compensate for manufacturing tolerances. Such an embodiment may also be used to rigidly form the head of the first component and without elastic arms provided on the head, as known from WO 2012/104250 A1. The object of the resilient arms of a head with regard to generating a contact pressure with which the two elements to be joined together are pressed together can also be achieved in the clip according to the invention by a correspondingly elastically ausgestaltetes second component. A contact force can be used to create a bias in the installed state. This can lead to a prevention of movement, or noise by external excitation such as vibrations, oscillations, relative movements.

In a preferred embodiment, the first component is made by bending from a metal blank. It has been found that such a manufacturing method is particularly suitable for producing a metal clip.

In a preferred embodiment, the contact surface of the second component facing the projection is a contact surface which extends annularly around the shaft axis. The ring may be both annular, as well as other ring shapes, such as those of an elliptical ring or that of a triangular or rectangular or polygonal ring. The formation of the contact surface of the second component facing the projection as a ring can be used particularly preferably for sealing purposes. The contact surface of the second component facing the projection is generally the contact surface which comes into contact with one of the two elements to be connected if the two elements to be connected are connected to one another by being between the contact surface of the second component facing the projection the provided on the projection of the first component contact surface are spent. Are in a particularly preferred embodiment, both elements to be connected equipped with a hole through which the shank of the first component of the two-part Clips is guided, so an annular contact surface on the second component can be used for sealing when it surrounds the opening in the one of the two elements to be connected. The provision of an annular contact surface can also serve to apply a uniform contact pressure on the elements to be joined together.

However, it is not absolutely necessary for the contact surface of the second component facing the projection to be an annular contact surface circulating around the shaft axis. The contact surface may also be a single self-contained surface. It is also conceivable that the second component has a plurality of contact surfaces, in particular a plurality of self-contained contact surfaces, which face the projection or the projections.

In a preferred embodiment, the second component has an upper part, which has a recess for receiving the head, and a lower part. Particularly preferably, the upper part and the lower part are parts of a one-piece element. Particularly preferably, the upper part and the lower part are separated from each other by a partition, wherein the partition wall forms the bottom of the recess and having the support surface facing the contact surface of the head. In a preferred embodiment, the lower part also has a recess whose bottom is the partition wall to the upper part. The recess of the lower part and the recess of the upper part thus open in a preferred embodiment in different directions.

In a preferred embodiment, the lower part is formed umbrella-shaped in its extension from the partition wall. In a preferred embodiment, the upper part has a rectangular cross section, wherein the rectangular cross section may also include rounded corners. In a preferred embodiment, a umbrella-shaped lower part continues the rectangular cross-section of the upper part such that each cross-section of the lower part also has a rectangular outer periphery, or has an outer periphery that is in its geometric shape, albeit not in size, the outer periphery of the upper part, while the size increases while maintaining the geometric shape of the outer circumference of the cross section of the lower part before each cutting plane to the next cutting plane which is farther away from the upper part increases.

In a preferred embodiment, a shield-shaped lower part of the second component has reinforcing ribs. These reinforcing ribs may for example be made of a different material than the remaining material of the lower part of the second component or differ from the remaining parts of the lower part of the second component in their material thickness. In the context of this description, one surface is considered to face another surface when the surface normal of one surface intersects the plane in which the other surface is located. In the course of the description of the present invention, the fact that the one surface faces the other surface does not require that the one surface can be brought into coincidence or overlap with the surface to which it faces by movement along its surface normal. In the course of this description, in order to be considered to be mutually facing surfaces, it is sufficient, for example, for the contact surface provided on the second component to be arranged in a plane perpendicular to the longitudinal axis (shaft axis) of the shaft and pointing in the direction of the tip. while provided on the projection of the shaft, the head facing Kohtaktfläche is also arranged in a plane which is perpendicular to the longitudinal axis (shaft axis) and facing the head, without that one surface of the other surface must be arranged opposite. In a preferred embodiment, the facing surfaces are arranged in parallel planes.

In a preferred embodiment, the head has a plurality of contact surfaces facing the projection and the second component has a plurality of support surfaces, wherein a support surface faces a contact surface of the head and a contact surface of the head is supported on a support surface of the second component. In this case, embodiments are also conceivable in which the support surface of the second component is chosen to be larger than the contact surface of the head and, for example, support two contact surfaces of the head on a support surface of the second component.

In a preferred embodiment, the second component has a plurality of contact surfaces facing the projection. Particularly preferably, at least one contact surface facing the projection is arranged on one side of a plane containing the shaft axis and another contact surface facing the projection on the other side of this plane.

In a preferred embodiment, a contact surface of the second component facing the projection is formed on a projection which projects from a main body, for example an upper part of the second component, which has a recess for receiving the head. The projection can be made of solid material. Likewise, the projection may be web-shaped or bridge-shaped or have two legs which meet in a point at which the projection facing the contact surface of the second component is provided.

Recesses may be provided in the head and the remainder of the structure of the clip may be selected such that a tool, such as a screwdriver or a point, can be passed from above through the head to a resilient element on which the projection is formed Opening in the head is chosen so large that it allows movement of the tool to retract the resilient member against its outward bias, thus retracting the projection on the shaft towards the middle of the shaft.

The second component may consist of two parts, a first part which has the contact surface of the head facing support surface on which the contact surface of the head is supported, and a second part which has the contact surface facing the projection. In a preferred embodiment, the first part of the second component is resiliently connected to the second part of the second component. In a particularly preferred embodiment, the first part of the second component has an opening through which the shaft is inserted, and / or the second part of the second component has an opening, is inserted through the shaft. In a preferred embodiment, both parts each have an opening through which shaft is inserted, wherein the first part of the second component has on one of its sides a bent portion which is connected to one side of the second part of the second component, wherein this bent Section produces the resilient connection between the two parts. In a preferred embodiment, the first part and the second part of the second component are made of metal or plastic.

the side surface of the head passes over a rounded edge into the tip-facing contact surface of the head, and / or

the first page merges into the first side wall via a rounded edge.

The use of the rounded edges avoids peaks, recesses or edges in these areas, which can damage the elements to be connected. In particular, in the embodiment in which the side surface of the head passes over a first rounded edge in the tip-facing contact surface of the head and the first side merges via a second rounded edge in the first side wall and the first rounded edge over an arc portion in the second rounded edge, the risk of injury of the two elements to be connected can be greatly reduced.

In the exemplary embodiment illustrated in the figures, the first side 4 and the second side 5 each have a flat main body. In Fig. 1 it can be seen that the otherwise flat base body 4 has a small elevation 31. This illustrates that used in the context of this description understanding of the term "flat body", which provides only in a particularly preferred embodiment, a geometrically exactly flat body, but in other embodiments - as here - referred to such basic body as a "flat body" due to smaller Projections deviate from a geometrically exactly flat shape.

In the embodiment shown in FIGS. Shown is the flat body of the first page 4 at an angle of 90 degrees to the flat body 9 of the first side wall 10. The flat body of the second page 5 is at an angle of 90 degrees to the flat body 12 of second sidewall 13. The first sidewall 10 and the second sidewall 13 are in alignment with each other (their outwardly facing surfaces are in a plane). The embodiment shown in the figures has four clip surfaces 40, 41, 42, 43. The respective clip surface is part of a resilient element which in each case by a recess 44, 45, 46, 47, in the respective transition between the side 4, 5 and the first side surface 10, the second side surface 13, the third side surface 50 and the fourth Side surface 51 is located, passes through. The respective elastic element has a chamfer 48 which causes the missing element, when the clip is inserted into a hole of an element, comes into contact with the edge of the hole and pushed inward against the spring force by the further insertion of the clip is, but springs back after passing through the hole in the element due to the spring force to the outside and thereby engages behind the corresponding element.

The clip surfaces 40, 41, 42, 43 face the head 1. The head has four head surfaces 55, 56, 57, 58, which face the clip surfaces 40, 41, 42, 43. The first member and the second member are held between the clip surfaces 40, 41, 42, 43 and the top surfaces 50, 56, 57, 58, thereby securing the second member to the first member.

The head 1 has a side surface 100 and the tip 2 facing contact surface (top surface) 55, wherein the side surface 100 of the head over a first rounded edge 101 in the tip 2 facing the contact surface 55 of the head merges and the first page 3 via a second rounded edge 102 merges into the first side wall 10 and the first rounded edge 101 merges via an arc section 103 into the second rounded edge 102. The tip 2 facing the contact surface 55 of the head 1 via an arc portion 104 in the first side wall 10 via.

In the following, three embodiments of a two-part clip according to the invention will be described, namely a first embodiment with reference to FIGS. 4 to 11, A second embodiment with reference to Figures 12 to 18 and a third embodiment with reference to Figures 19 and 20. All three two-part embodiments have in common that their first component is a one-piece clip, as described above with reference to Figures 1 to 3.

The two-part clip shown in FIGS. 4 to 11 for fastening an element to another element has a first component which corresponds to the clip shown in FIGS. 1 to 3 and has a head 1 and a tip 2. Between the head 1 and the tip 2 there extends a shaft 3 composed of several sections. There are four projections on the shaft 3, each projection being formed by a part of a resilient element passing through a recess 44, 45, 46, 47 engages in the shaft 3. In the form of the four clip surfaces 40, 41, 42, 43, the projections each have a contact surface facing the head 1. The head 1 has four top surfaces (contact surfaces) 55, 56, 57, 58 which face the projections. Since the projections are part of the resilient elements, they can be moved under forces against an increasing spring force from the rest position shown in FIG., The spring force causes the projections returns to its rest position after elimination of the force. The rest position is the position in which the resilient element exerts no force.

The two-part clip has a second component 60. The second component has four support surfaces 61, 62, 63, 64 (compare FIGS. 10 and 11). Each support surface 61, 62, 63, 64 of the second component 60 faces one of the contact surfaces of the head formed as head surfaces 55, 56, 57, 58, wherein the respective contact surface (head surface) 55, 56, 57, 58 of the head 1 the respective support surface 61, 62, 63, 64 is supported. Furthermore, the second component 60 has a contact surface 65, which faces the projections. The contact surface 65 of the second component 60 is designed as a rectangular ring with rounded corners.

The second component 60 has an upper part 66 which has a constant outer contour and a lower part 67, which widens umbrella-like towards the tip 2 and terminates in the contact surface 65 facing the projections.

The second component 60 has an opening through which the shaft 3 is inserted. The opening 68 is made at the bottom of a recess 69 of the second component 60. The recess 69 of the second component 60 receives the head 1. In this case, the recess 69 is so deep that when the contact surfaces 55, 56, 57, 58 of the head 1 are supported on the respective support surfaces 61, 62, 63, 64, the head 1 no longer protrudes from the recess 1 (see, for example FIGS. 4 and 5). In the illustrated in the embodiments of Figures 4 to 1 1 and 12 to 18 both Embodiments, the head 1 is flush with the recess 69 delimiting edge of the second component 60 from.

In the two exemplary embodiments according to FIGS. 4 to 11 and 12 to 18, the first component of the two-part clip (which is described in greater detail with reference to FIGS. 1 to 3) is made of metal, while the second component 60 (FIGS ), or 70 (Figures 12 to 18) is made of plastic.

The second component 60 has two projections 99 which project into the opening 68. These projections 99 of the second component 60 serve as captive. As the Fig.

6, the projection 99 engages a recess on the first component and comes into contact with the edge of the recess of the first component. The interaction between the projection 99 and the edge of the recess of the first component prevents the second component 60 from moving in the direction of the tip 2.

The second component 70 of the second embodiment of the two-part clip shown in Figures 12 to 18 differs from the second member 60 according to Figures 4 to 1 1 by the design of the lower part 77 and the support surfaces and the opening, which penetrated from the shaft becomes. The second

Component 70 of the embodiment according to FIGS 12 to 18 has support surfaces 71, 72, 73, 74, wherein the support surface 71 merges into the support surface 72 and the support surface 73 merges into the support surface 74. Each support surface 71, 72, 73, 74 of the second component 70 faces one of the contact surfaces of the head formed as head surfaces 55, 56, 57, 58, the respective contact surface (head surface) 55, 56, 57,

58 of the head 1 on the respective support surface 71, 72, 73, 74 is supported. Furthermore, the second component 70 has an opening 78 and a recess 79 which correspond to the opening 68 and the recess 69. While the embodiment according to FIGS. 4 to 11 has an annular contact surface 65, the second embodiment according to FIGS. 12 to 18 has four contact surfaces 75. The respective contact surfaces

75 are formed on projections of the second component 70. The projections are bridge-shaped and have two legs which meet in a point at which the projection facing contact surfaces 75 of the second component 70 are provided.

The third embodiment illustrated with reference to FIGS. 19 and 20 differs in particular from the other two embodiments in three respects (FIGS. 4 to 18). On the one hand, the second component 80 has no recess which receives the head 1. Further, the second component 80 is also made of metal, as is the first component of this third embodiment.
